Maintenance Oil Pump
oil pump's working Stable, for the stability of the normal operation of the device is the most critical, a lot of equipment are due to problems caused by the oil pump, but for oil pump some common problems many people do not understand, for the maintenance of methods do not understand, this will only work on the production and normal bring great disadvantage. So common problems and repair methods are what, how are we going maintenance and repair it?
engine oil pump can work reliably in fact lies in the main piston and the guide sleeve to take the clearance fit is qualified standard, the general piston and the guide sleeve for the radial clearance is only a few microns, if one of the gap is too large, will cause a large degree of leakage of fuel, but this time the engine will cause the start up difficult.
If the auto oil pump lubrication performance is poor, it would very easily result in high pressure pump plunger and bushing wear between the parts, so be sure to carry out this timely inspection and maintenance, the old must be replaced, failed the also new ones, so that the normal production and work are carried out.
oil pump will pump problems, mainly due to the pumping chamber caused by the internal pressure drop, at this time the oil pressure of the spring under the valve will automatically close, which avoids the outlet valve not easily leak.
